ARTICULATED JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 558,642, dated April 21, 1896. Application filed January 17, 1896. Serial No. 575,835.. (No model.) Patented in France October 23, 1898, No. 238,584.

To all whom it may concern:

Be it known that I, AMEDFJE FAYOL, a citizen of the Republic of France, residing at 10 Rue Belleville, Bordeaux, France, have in vented certain new and useful Improvements in Articulated Journal-Boxes, (patented in France October 23, 1893, No. 233,584,) of which the following is a specification.

My invention relates to journal-boxes, and has for its object to produce an efficient and reliable articulated j ournal-box.

My invention consists in the construction hereinafter set forth and claimed.

My invention will be understood by reference to the accompanying drawings, in which- Figure 1 is a side view of a journal-box embodying my invention. Fig. 2 is an end View thereof. Fig. 3 is a longitudinal section thereof, taken 011 the line 3 of Fig. 2. Fig. at is a transverse section taken on line 4 4 of Fig. 3. Fig. 5 is a detail view of a temperedsteel ring or envelop hereinafter described. Fig. 6 is a longitudinal sectional View of another form of journal-box embodying my invention. Fig. 7 is a section thereof on the line 7 7 of Fig. 6, and exhibits also the section, line 6 6, 011 which the section of Fig. 6 is taken. Fig. 8 is a longitudinal sectional view of another form of j ournal-box embodying my invention. verse section thereof.

In the drawings, f is the axle or journal arm or other shafting. r

a is the axle-box or journal-box which is capped by checks 0 b, the cheek Z) being faced by a tempered-steel facing-plate o, the whole being held together by bolts a. This journalbox a has a central opening therethrough in which the sleeve or box (1 is seated, which is faced on the inside by a tempered-steel facing ring m, thus dispensing with the necessity of tempering thesleeve or box (Z. Surrounding the axle-arm f is an envelop-ring or wearplate 02, of tempered steel, which is shown in detail in Fig. 5, the said ring being cut on the lines a n and clamped around the axlearm f, thus dispensing with the necessity of tempering or case-hardening the axle-arm.

, Interposed between the rings m n and taking up the friction and bearing of the parts, one on the other, is a series of rollers g h, which Fig. Ois a central transentirely occupy the annular space intervening between the rings on and 72.. These cylinders or rollers are trued perfectly, so that they will maintain absolute parallelism at all times with one another and the axis of the axle-arm, so that there will be no binding, thus obviating unnecessary friction, and will also preserve the absolute concentricity of the axlearm and box. These rollers are of different sizes, the rollers 9, being bearing-rollers, are of a diameter equal to the normal width of the annular space between the rings. These bearing-rollers g alternate with smaller free guiding-rollers 71, parallel to the axes thereof, which do not carry the weight which the rollers g carry, but which, touching the rollers 9 along the lines of their axis, serve to guide the rollers g and preserve their parallelism. The interactions of the rollers, axlearm, and box will be understood without explanation.

The sleeve or box (Z contacts with the walls of the box a and is convexly curved 011 its outer surface after the manner of a fingerring or the figure generated by the revolution of a convex curve (see Fig. 3)-that is to say, the greatest diameter of the sleeve or box is about the middle thereof on a plane at right angle to its axis, the least diameter being at the edges of the sleeve. Other convex forms may, however, be adopted. This convexity of the sleeve permits the axes of the box a and the axle-arm f to change their relations of parallelism, the aperture a through which the axle-arm f passes being of sufficient size to permit such action.

In the modification shown in Figs. 6 and 7 the axle-box a is square instead of round, as in the former modification, but is capped as before with the apertured cheek c at one end, the cheek b at the other end, which cheek Z) is provided on its inner face with a tempered facing plate 0 against which the axle or journal arm f bears. The checks and box are held in position by the bolts o A squared sleeve d is carried in the box a and has its inner face, which is circular, faced with the tempered-steel facing-ringm, the aXlearmf being also enveloped by the tempered-steel ring 11. In the annular space between the rings or and n I place rollers g, whose diameter equals the space between the rings on" and n, so as to keep the parts concentric.

These bearing-rollers g alternate with smaller guiding-rollers h, which do not carry the weight which the rollers g carry, but which serve to guide the rollers g and preserve their parallelism. The upper and lower surfaces 1 and Q6 of the sleeve d are curved in the same manner as the exterior surface of the sleeve d in Fig. 3, thus permitting the axes of the box a and the axle or journal arm f to change their relation of parallelism, the aperture in the cheek 0 through which the axle-arm f passes being of sufficient size to permit such action. I

The modification shown in Figs. 8 and 9 is of the same general character as the modification shown in Figs. 6 and 7, the box a being square inside and provided with the apertured cheek c and the cheek 12 whose inner face is faced with the tempered-steel plate 0 against which the axle-arm f bears, bolts a serving to hold the parts together, as before. (1 is the sleeve whose circular orifice is faced with a tempered-steel plate m as before, and which is provided with trunnions t,which rest in bearings a in the box a The axle-arm f is also faced with the tempered-steel sleeve or facing-ring it and intervening between the sleeves m 'and n are the bearing-rollers g and guiding-rollers 71 as in the former cases.

It will be obvious that these last two modifications are variations of the articulate feature of the journal-box and have no reference to the antifriction feature as exemplified in the rollers.

V hat I claim, and desire to secure by Letters Patent, is-

1. The combination with an axle-arm, of a sleeve or box surrounding the said arm, and bearing-rollers in the space between the arm and the sleeve or box, which rollers bear the strain, are absolutely free to move and are smooth and cylindrical from' end to end, guiding-rollers also absolutely free to move, smooth and cylindrical from end to end, interposed between and axially parallel to adjacent bearing rollers and touching them along the lines of their axes, the exterior surface of the said box or sleeve which confines the rollers and surrounds the axle-arm being convexly curved axially, the said box being combined with and resting in a second box or frame on the line of an arc of a circle in such'a manner that it may incline in various directions with relation to the box or frame in which it rests, substantially as described and for the purpose specified.

2. An interior rectangular movable box curved axially, and having trunnions rigidly connected thereto and projecting straight from its sides, which trunnions provide articulation, combined with and carried within an exterior box of rectangular opening and provided with bearings receiving the trunnions, substantially as described and for the purpose specified. p

3. The combination of the smooth differential rollers, the journal, the movable articulated box or sleeve, the exterior fixed box, and facing-rings of tempered steel on the contact-surfaces, whereby tempering or casehardening the contact-surfaces is rendered unnecessary, substantially as described and for the purpose specified.

4. The herein-described articulated antifriction-bearing consisting of the combination of an axle-arm, a square sleeve or box surrounding the said axle-arm and provided with trunnions, a series of bearing-rollers interposed between the axle-arm and the sleeve or box, a series of smaller guiding-rollers interposed between the rollers and running-in the annular space between the axle-arm and the sleeve or box, a square box surrounding the said sleeve and provided with bearings for the trunnions of the box, cheeks forming the ends of the box, and bolts for holding the cheeks up to the edges of the box, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
